Fix build with Qt version 5.2, regarding QAtomicInteger include
Review Request #120044 - Created Sept. 3, 2014 and submitted
There is an include for QAtomicInteger which does not check the version of Qt. Looks like QAtomicInteger appeared starting with 5.3. Placed a similar #ifdef check to one found in the same file.
Previously Akonadi did not build with Qt 5.2
Now it builds fine for me.
